i\'m working with opengl and texture mapping. the problem is when the applied texture is 512×32 pixels every thing is working fine, but when it\'s 128×128 the texture is not applied properly.
I have a series of CSV files of timestamped coordinates (X, Y, and Z in mm). What would be the simplest way to extract motion data from them?
The situation is as follows: There are N arrays. In each array (0..N-1) there are (x,y) tuples (cartesian coordinates) stored
i have a table with two fields (X,Y) they hold the location of points in New Israel Projection (EPSG: 2039) (e.g. X=194545.05941493041, Y=668112.83849507652)
I want to get the latitude and longitude on a 3D sphere, depending on Mouse X,Y. Iv\'e understood that i have to use trigonometry. The problem is that the spher开发者_C百科e is put into a perspective,
I am trying to get the window coordinates of a table view using the following code: [开发者_运维知识库self.tableView.superview convertRect:self.tableView.frame toView:nil]
this is my first participation in the list, I\'m the following problem, I have a dynamic query that will always me return an array with n elements, like the example below:
Is there a way 开发者_运维问答to get the screen coordinates of the objects in the 3d world?Implement gluProject().
After doing rotating and translating using CompositeTransform. The coordinates for the shapes remain the same in both messagebox.
In OpenGL, I am trying to invert the y axis, and set a specific type of coordinate system just like how Allegro has it. Assuming my window is 640x480, I want the top left of the screen be axis (0, 0),
